JOHN H. KANE, on PITTSBUBG, PENNSYLvANIA.

HYDRAULIC ENGINE.

SPECIFICATION forming part of Letters Patent No. :225,614, dated March 16, 1880.

Application filed October 31, 1879.

To all whom qit may concm Be it known that I, JOHN H. KANE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hydraulic Engines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this spccitication.

My invention relates to an improvement in hydraulic engines, its object being to produce an oscillating motion by means of hydraulic pressure.

To attain this end this invention consists of a piston at the end of an arm attached to a vertical journaled shaft, whicli'piston" and arm are made alternately to move first in one direction, and when arrived at a certain point to return to its starting-place, as will be more fully described hereinafter.

The accompanying drawings represent my invention.

Figure 1 is a plan view with the cover removed, and Fig. 2 is a vertical section.

A represents a vertical shaft journaled in the center of a cylinder, B. Within the cylinder B is a smaller concentric chamber, C, leaving room for a water-way, D, between the circumferenoes of the outer cylinder and the inner chamber.

In the water-way D a stationary transverse wall, E, standing between the valve-ports a a', forms the starting-point, from which and to which the piston F, at opposite sides, oscillates. The piston F is secured to the outer end of a horizontal arm, G, that extends through an enlarged ,portion of the central shaft, the piston occupying transversely the 4 water-way D.

'cap of the cylinder.

ton F, and, after passing through the central shaft, the inner end of the arm is secured at the opposite side in the ring H. Thus the piston, ring, and shaft are made to move together.

Water is alternately admitted and expelled through the port-holes a a', controlled by valves b b' at the outside of the cylinder B, which valves may be worked by means of a ratchet and lover, or in any other suitable manner. v

A tube, J, connected with the water-pipe L, and passing through the cap on the cylinder B into the chamber C, keeps this chamber filled with water, to counter-act the pressure exerted by the water in the water-way against the wall of the chamber. e

The vertical central shaft is pivoted on the point of a set-screw under the cylinder, and raised or lowered, as may be required, to regulate the movement of the piston.

On the cap surrounding the central shat't is a suitable arrangement for packing to pre vent leakage.

A proper connection being made by means of the bevel-wheel M on the central shaft, the operation is as follows: One of the valves is opened to admit the water, which, filling the waterwvay behind the piston, pushes the piston until it has arrived at or near one side of the Wall E, when, through the second Valve, water is admitted, pressing against the side of the piston opposite to that against which the pressure at first was exerted. At the same time the port ot' the valve first used, being open, allows the water which has already performed its service to escape.

The same operation is continued, alternately admitting water at one side and eX- pelling it at the other, and, by closing the valves admitting water, the engine may be arrested at any point, and again set in motion by opening either one of the valves.

Having thus described my invention, I claim 1. The combination of the shaft A, cylinder B, inner chamber, C, piston F, arm Gr, Wall E, and packing ring H, arranged and operatin g substantially as described.

2. In an oscillating hydrmlio engine, the In testimony that I claim the foregoing I shaft A, combined With arm G, piston F, and have hereunto set my hand this 25th day of open packing-ring H, substantial'ly as shown October, 1879. and described.
